nZEB Design in Buildings

Posted Posted in News

nZEB ( Nearly Zero Energy Building standard) is the European Energy Performance of Buildings Directive Recast 2010 (EPBD). It requires all new buildings to be nearly Zero Energy Buildings (nZEB) by 31st December 2020 and all buildings acquired by public bodies by 31st December 2018. This standard is now being applied to all relevant building designs and requires buildings designers and owners to achieve 20% of their primary energy needs from renewable sources on site or nearby. Callaghan Engineering have undertaken nZEB design on 5 school projects over the past 3 months to bring the already completed designs up to the required Part L of the building regulations 2017 for buildings other than dwellings. Central to the design process is the development of a new thermal model to test that with improved design elements for insulation u-values, airtightness, thermal bridging,  glazing and using 10% renewable energy contribution we are achieving the necessary reduction in energy demand compared to a similar building prior to nZEB (reference building). With the design teams , Callaghan Engineering achieved the necessary nZEB changes through the use of photovoltaic cells on the roof and improved u-values in walls, glazing, floors and roof.

Major pharma and medtech project wins for Callaghan Engineering

Posted Posted in News

Callaghan Engineering continue to standout as one of Ireland’s leading process engineering consultancies having had significant recent wins in both  pharma and medtech sectors in 2018 and into 2019.

Pharma Milling

Callaghan Engineering are project managers and lead designers for a substantial milling and dispensing upgrade project incorporating very high technology containment techniques. This project is taking place within an existing manufacturing facility and will require close coordination between all stakeholders to minimise disruption to existing operations during installation. The drug in manufacture is a statin medication used to prevent cardiovascular disease in those at high risk and treat abnormal lipid levels. This project is being delivered in the Munster region for a confidential client – value €2.2m.

Filter Media

This project encompasses a new building on an existing site for the manufacture of filter media for filter cartridges used throughout industry. The new building will contain cleanroom manufacturing facilities together with plantroom, and connections to existing utilities, and also the on-site thermal oxidiser. The project involves refurbishment of some existing processing facilities. It is located in the Munster region and will be delivered in 2019/20, and is valued at approximately €30m. Callaghan Engineering are the process, mechanical and electrical engineering designers for the project. This will also include leading compliance issues and conducting HAZOP reviews.

Diagnostics Solutions

A major expansion of an existing diagnostics manufacturing facility is currently underway in the Midlands area and is scheduled to be completed in 2019. The project involves a significant extension to the existing facility and includes process tanks, cleanroom facility, and 4 vial filling lines (Argon inerting) with a capacity for 1 million vials/year. The overall investment is approximately €20m. Callaghan engineering have led the mechanical and electrical engineering design and some elements of the process engineering.

Clifden Community School

Clifden Community School

Callaghan Engineering were responsible for the M&E Design from concept stage to building completion.   The post primary school is a two-storey and part 3-storey L-shaped building with a floor area of 3852 square metres located on this spectacular sloping site outside Clifden town.  Works also included the demolition of the existing school building and associated pre-fabricated classroom structures once the new school was fully operational. One of the main challenges for this project was that the existing school building had to be kept operational while the new school was built on the same site. The building was completed on time and within budget and will cater for 425 pupils and 38 staff.
